Description

Technical Field

[0001] This utility model belongs to the technical field of filtration, specifically relating to a self-rotating multi-stage filtration and purification device. Background Technology

[0002] The self-rotating multi-stage filtration and purification device is a high-efficiency and energy-saving fluid treatment equipment, mainly used in water treatment, air purification and industrial fluid separation. Its core design uses self-rotation power to drive multi-stage filtration units to work together, combining physical interception, adsorption and centrifugal separation technologies to remove particulate matter, microorganisms and dissolved pollutants from the fluid step by step.

[0003] Currently, when cleaning the filter screen, the scraper is easily entangled or stuck by fibrous impurities or sticky dirt, which can obstruct the movement of the blade or even completely jam it. This not only reduces the self-cleaning efficiency but may also damage the drive mechanism due to motor overload. Such problems are particularly prominent when filtering high-viscosity fluids (such as oily wastewater) or materials containing long fibers (such as pulp wastewater). Because the jamming process occurs gradually, it is not easily detected by the sensor in the early stages and is often only discovered when the scraper has completely stopped moving, affecting the continuous operation of the system. Utility Model Content

[0004] The purpose of this invention is to provide a self-rotating multi-stage filtration and purification device, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-rotating multi-stage filtration and purification device, including:

[0007] The support mechanism includes a bracket and a filter cartridge shell fixedly installed inside the bracket.

[0008] The anti-jamming mechanism includes a tube fixedly installed on the top of the filter cartridge shell, a sealing plate fixedly installed on the top of the tube, an anti-winding component disposed below the sealing plate, a cylinder fixedly installed on the bottom of the sealing plate, and an elastic telescopic rod fixedly installed in the inner cavity of the cylinder.

[0009] As a preferred embodiment of this utility model, the anti-jamming mechanism further includes a limiting disc movably sleeved on the outside of the elastic telescopic rod, a rubber elastic block fixedly installed at the end of the elastic telescopic rod, and a connecting disc fixedly installed at the bottom of the rubber elastic block.

[0010] In a preferred embodiment of this utility model, the number of elastic telescopic rods is three, and they are evenly distributed in a ring shape within the inner cavity of the cylinder.

[0011] As a preferred embodiment of this utility model, the anti-winding component includes a disc body fixedly installed at the bottom of the rubber elastic block, a crossbar fixedly installed at the bottom of the disc body, and a scraper fixedly installed at the bottom of the crossbar.

[0012] As a preferred embodiment of this utility model, the anti-winding component further includes a guide plate fixedly installed at the bottom of the disc body, and a cutting blade fixedly installed at the bottom of the disc body.

[0013] In a preferred embodiment of this utility model, the cutting blade is fixedly installed at an inclined angle, there are two crossbars installed longitudinally, and there are two guide plates installed laterally.

[0014] As a preferred embodiment of this utility model, the supporting mechanism further includes an outlet pipe fixedly installed on one side of the filter cartridge shell, an inlet pipe fixedly installed on the other side of the filter cartridge shell, a drive motor fixedly installed on the outside of the filter cartridge shell, and a maintenance and drainage plate hinged to the bottom of the filter cartridge shell.

[0015] Compared with existing technologies, the advantages of this invention are as follows: An adaptive pressure adjustment system is formed by three ring-shaped elastic telescopic rods in conjunction with rubber elastic blocks, ensuring that the scraper always maintains optimal contact pressure with the filter screen; the synergistic effect of the inclined cutting blade and guide plate actively cuts and guides long fiber impurities, preventing entanglement and accumulation; the cooperative design of the limiting disc and connecting disc avoids mechanical damage caused by excessive extension and retraction; for high-viscosity fluids and materials containing long fibers, the mechanical self-adjustment mechanism solves the problem of gradual jamming being difficult to monitor, significantly improving self-cleaning efficiency and system reliability, while reducing the risk of motor overload and ensuring continuous and stable operation of the filtration system.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example

[0028] Reference Figures 1-4 This is an embodiment of the present invention, which provides a self-rotating multi-stage filtration and purification device, including:

[0029] The support mechanism 100 includes a bracket 110 and a filter cartridge shell 120 fixedly installed in the inner cavity of the bracket 110;

[0030] The anti-jamming mechanism 200 includes a tube 210 fixedly installed on the top of the filter cartridge shell 120, a sealing plate 220 fixedly installed on the top of the tube 210, an anti-winding component 230 disposed below the sealing plate 220, a cylinder 240 fixedly installed on the bottom of the sealing plate 220, and an elastic telescopic rod 250 fixedly installed in the inner cavity of the cylinder 240.

[0031] The device features a stable support structure and anti-clogging function thanks to the support mechanism 100 and the anti-jamming mechanism 200. The filter cartridge 120 is fixed inside the bracket 110 to ensure the overall structure is stable. The anti-jamming mechanism 200, through the cooperation of the tube body 210, the sealing plate 220, and the anti-winding component 230, effectively prevents the accumulation of fibers or sticky impurities and improves filtration efficiency. Meanwhile, the elastic telescopic rod 250 can adaptively adjust the scraping force to reduce the risk of jamming.

[0032] Specifically, the anti-jamming mechanism 200 also includes a limiting disc 260 movably sleeved on the outside of the elastic telescopic rod 250, a rubber elastic block 270 fixedly installed at the end of the elastic telescopic rod 250, and a connecting disc 280 fixedly installed at the bottom of the rubber elastic block 270. There are three elastic telescopic rods 250, which are evenly distributed in a ring in the inner cavity of the cylinder 240.

[0033] The anti-jamming function is further optimized by adding a limiting disc 260, a rubber elastic block 270, and a connecting disc 280. The limiting disc 260 can limit the displacement range of the elastic telescopic rod 250 to avoid structural damage caused by excessive extension and contraction; the rubber elastic block 270 provides a buffering effect to reduce impact vibration; the connecting disc 280 ensures stable operation of the scraping assembly and extends its service life; the use of three ring-shaped distributed elastic telescopic rods 250 makes the anti-jamming mechanism 200 evenly stressed, avoiding wear or deformation caused by unilateral load, enhancing the balance and reliability of the structure, making it suitable for high-speed rotation conditions, and facilitating maintenance and replacement.

[0034] Furthermore, the anti-winding assembly 230 includes a disc 231 fixedly installed at the bottom of the rubber elastic block 270, a crossbar 232 fixedly installed at the bottom of the disc 231, and a scraper 233 fixedly installed at the bottom of the crossbar 232. The anti-winding assembly 230 also includes a guide plate 234 fixedly installed at the bottom of the disc 231, and a cutting blade 235 fixedly installed at the bottom of the disc 231. The cutting blade 235 is fixedly installed at an inclined angle. There are two crossbars 232 installed longitudinally, and there are two guide plates 234 installed laterally.

[0035] The anti-winding component 230, through the synergistic action of the disc 231, crossbar 232, and scraper 233, can efficiently remove impurities from the filter screen surface. The scraper 233 fits tightly against the filter screen to ensure cleaning effect. The crossbar 232 provides rigid support to prevent the scraper 233 from deforming, which is especially suitable for filtering high-viscosity or fibrous fluids. The guide plate 234 and the cutting blade 235 further enhance the anti-winding capability. The guide plate 234 guides impurities to the cutting blade 235 to avoid accumulation. The inclined cutting blade 235 can cut long fibers or sticky substances to prevent entanglement and significantly reduce the frequency of downtime cleaning. By optimizing the tilt angle of the cutting blade 235 and the layout of the crossbar 232 and guide plate 234, the efficiency and targeting of impurity treatment are improved. The combined design of the longitudinal crossbar 232 and the transverse guide plate 234 ensures that impurities are effectively intercepted and cut, while reducing fluid resistance and maintaining stable filtration flow.

[0036] Preferably, the support mechanism 100 also includes an outlet pipe 130 fixedly installed on one side of the filter cartridge housing 120, an inlet pipe 140 fixedly installed on the other side of the filter cartridge housing 120, a drive motor 150 fixedly installed on the outside of the filter cartridge housing 120, and a maintenance drain plate 160 hinged to the bottom of the filter cartridge housing 120.

[0037] The supporting mechanism 100 integrates the water outlet pipe 130, the water inlet pipe 140, the drive motor 150, and the maintenance and drainage plate 160, achieving multi-functional integration. The water outlet pipe 130 and the water inlet pipe 140 optimize the fluid path, the drive motor 150 provides stable power, and the articulated maintenance and drainage plate 160 facilitates quick cleaning and maintenance, significantly improving the operational convenience and overall efficiency of the device.

[0038] During use, the fluid first enters the filter cartridge housing 120 through the inlet pipe 140. Driven by the drive motor 150, the anti-jamming mechanism 200 starts to rotate. The scraper 233 in the anti-winding component 230 continuously scrapes away impurities from the filter screen surface, the inclined cutting blade 235 cuts long fibers, and the guide plate 234 guides the impurities to the drain port. The elastic telescopic rod 250 adaptively adjusts the pressure under the buffering effect of the rubber elastic block 270 to ensure that the scraping force is moderate. The filtered clean fluid is discharged from the outlet pipe 130, while the trapped impurities are periodically removed through the easily openable maintenance drain plate 160, realizing continuous and efficient self-cleaning filtration cycle.

[0039] In summary, the supporting mechanism 100 adopts a rigid connection between the bracket 110 and the filter cartridge shell 120 to ensure the overall structure is stable and reliable; the anti-jamming mechanism 200, through the coordinated cooperation of the tube body 210, the sealing plate 220 and the anti-winding component 230, combined with three ring-shaped elastic telescopic rods 250 and their limiting discs 260, rubber elastic blocks 270 and other components, effectively solves the problem of fiber and sticky impurities jamming, significantly improving filtration efficiency and service life; the anti-winding component 230 is equipped with a scraper 233, a guide plate 234 and an inclined cutting blade 235, which can efficiently remove and cut impurities, and has outstanding advantages such as reasonable structure, excellent anti-clogging performance and convenient maintenance, and is suitable for handling fluid filtration conditions with high viscosity or fibrous impurities.
